Question Consider a corn yield of 7,200 kg/hectare (equivalent to 120 bushels per acre). If 25 kg (one bushel) of corn consumed about 20 m 3 of water during the growing season, what is the ratio of the weight of corn to the weight of water consumed? Where does the water end up? Calculate the minimum quantity of i rrigation water required to grow the corn (1 hectare = 10 4 m 2 ) if the corn is grown in Phoenix, AZ (annual precipitation 8.04 in) or in Lincoln, NE 31.0 in). Clearly state any assumptions you make.
